How
I built a Mash/Lauter Tun |
|
|
|
|
|
|

It was pretty easy.
As you can see from the pictures below. All I used was some 1/2"
copper tubing and some 90 and 45 degree elbows a few T's and 2 female
threaded attachments. For the spigot I used a brass valve, a brass
close nipple a few Stainless steel washers and silicone O-Rings. Below
are better Descriptions. |

The complete Mash/Lauter
Tun. |

Here is the manifold
at the bottom of the tun that will filter out the grains. Depending
on the size of the cooler used cut the copper tubing to length. I
used 4 elbows on the frame and 3 t's. One facing up for the connector.
For the connector I used 1 90 degree elbow right off the T connection
and 2 45 degree connectors to form sort of a backwards Z so it came
to the right spot on the cooler to meet up with the hole. I used copper
bond epoxy which is good up to 185 degrees. The mash should not get
that high so things should be OK. Copper Bond is supposed to act exactly
the same as soldering the joints. After it is assembled and bonded,
I cut slits in the manifold with a hacksaw. To the right you can see
the positioning in the cooler. |

For the spigot I
just used a 1/2" brass close nipple, 1 5/8" Stainless Steel
Washer, a 1/2" brass ball valve, and a 90 degree 1/2" to
3/8" hose barbed hose adapter. The other side of the close nipple
threads onto the manifold at the other end. There is a silicone gasket
on this side as well right behind the washer. |

Although I batch
Sparge now, when I started I was Fly Sparging. If you want to Fly
Sparge you can build a sparge Manifold like the one to the right.
I built the sparge manifold the same way as the bottom, except I drilled
holes for the water to shower down onto the grainbed and the T pointing
up is connected to a straight piece of copper that goes through the
lid and to another 1/2" female adapter and a 1/2" to 3/8"
hose adapter. Except it is straight through instead of angled to meet
the hole like in the bottom. Below is a pick of the top of the tun.
Just the flip side of the lid pictured on the right. |
